Objective: To explore the feasibility of synthetic magnetic resonance imaging (syMRI) combined with clinicopathological characteristics for the pre-treatment prediction of chemoradiotherapy (CRT) response in advanced nasopharyngeal carcinoma (ANPC). Materials and Methods: Patients with ANPC treated with CRT between September 2020 and June 2022 were retrospectively enrolled and categorized into response group (RG, n = 95) and non RGs (NRG, n = 32) based on the Response Evaluation Criteria in Solid Tumors (RECIST) 1.1. The quantitative parameters from pre-treatment syMRI (longitudinal [T1] and transverse [T2] relaxation times and proton density [PD]), diffusion-weighted imaging (apparent diffusion coefficient [ADC]), and clinicopathological characteristics were compared between RG and NRG. Logistic regression analysis was applied to identify parameters independently associated with CRT response and to construct a multivariable model. The areas under the receiveroperating characteristic curve (AUC) for various diagnostic approaches were compared using the DeLong test. Results: The T1, T2, and PD values in the NRG were significantly lower than those in the RG (all P < 0.05), whereas no significant difference was observed in the ADC values between these two groups. Clinicopathological characteristics (Epstein–Barr virus [EBV]-DNA level, lymph node extranodal extension, clinical stage, and Ki-67 expression) exhibited significant differences between the two groups. Logistic regression analysis showed that T1, PD, EBV-DNA level, clinical stage, and Ki-67 expression had significant independent relationships with CRT response (all P < 0.05). The multivariable model incorporating these five variables yielded AUC, sensitivity, and specificity values of 0.974, 93.8% (30/32), and 91.6% (87/95), respectively. Conclusion SyMRI may be used for the pretreatment prediction of CRT response in ANPC. The multivariable model incorporating syMRI quantitative parameters and clinicopathological characteristics, which were independently associated with CRT response, may be a new tool for the pretreatment prediction of CRT response.

Objective:To investigate the clinical efficacy of individualised microvascular decompression (MVD) for trigeminal neuralgia (TN), so as to provide individualised treatment strategies and new thoughts for treatment.Methods:Clinical data of 46 patients who had TN and treated in the Department of Neurosurgery at the First Affiliated Hospital of Anhui Medical University from January 2021 to September 2023 were retrospectively studied. The study consisted of 19 males and 27 females, with an average age of morbidity at (58.3 ± 9.0) years old. Preoperative pain ratings and surgical outcomes were evaluated using the Barrow Neurological Institute (BNI) pain rating scale, and of which 27 patients were rated at BNI grade IV and 19 at grade V before surgery. A posterior trans-sigmoid sinus approach was applied in surgery on all patients, which could be performed in various ways depending on the vascular conditions identified during surgery. Ten patients were treated with microsurgery, 12 with endoscopic surgery and 24 with combined endoscopic surgery and microsurgery. After having identified the responsible vessel(s), a vascular decompression for the affected trigeminal nerve was performed and the nerve decompression was achieved by a polyester pad. Long-term postoperative follow-ups were conducted via telephone interviews or outpatient visits.Results:A total of 46 patients received the microvascular decompression surgery. Among them, 43 cases (93.5%) achieved immediate and complete pain relief of BNI grade I after surgery, and 3 cases (6.5%) achieved partial pain relief of BNI grade Ⅱ. Four patients developed facial numbness and sensory reduction, 2 developed facial paralysis (of House-Brackmann grade Ⅱ of 1 patient and grade Ⅲ of the other), 8 developed pneumocephalus, 4 developed postoperative fever, and 2 developed subcutaneous effusion. After treatment, the pneumocephalus and fever were cured, subcutaneous effusion was disappeared in 1 patient, but remained in the other. The mean follow-up period for the 46 patients was 16.2 (1-33) months. During the follow-up, 2 of the 3 patients of BNI grade Ⅱ immediately after surgery had complete remission to BNI grade Ⅰ and the other had recurrence and aggravation at BNI grade Ⅳ.Conclusion:The complexity of the responsible vessels is one of the important factors to be considered in the microvascular decompression strategy for trigeminal neuralgia. An individualised surgical plan according to a specific vascular condition identified in the surgery, is a best possible or worthiness surgical strategy in the treatment for a TN.

Objective:To comprehensively search the relevant literature on prone position-cardiopulmonary resuscitation (PP-CPR) in adults at home and abroad, analyze the content, summarize the evidence, and provide reference for clinical health care professionals.Methods:Systematic search of CNKI, China Biomedical Literature Service System (SinoMed), Wanfang Data, VIP database, PubMed, Embase, Cumulative Index to Nursing and Allied Health Literature (CINAHL), Cochran Library, Web of Science, Scopus literature database and other Chinese and English databases was conducted. The search period was from inception to June 15 in 2024. The contents of PP-CPR from randomized controlled trial (RCT), non-RCT (prospective or retrospective), cohort studies and case reports were extracted and systematically analyzed. The search results were standardized by the method of scoping review.Results:A total of 523 articles were obtained through preliminary search, and 14 references and gray literature were retrieved, totaling 537 articles. After strict screening by two researchers, a total of 26 literatures were included, 3 were non-RCT and 23 were case reports, involving 12 countries, including 3 in Chinese, 19 in English, 2 in French, 1 in German, and 1 in Korean. Three non-RCT demonstrated that compared with standard cardiopulmonary resuscitation (CPR), PP-CPR could produce higher pressure, and provide good respiratory and circulatory support. A total of 25 adult patients were included in the 23 case reports, of which 17 reported total recovery time and 13 reported PP-CPR time ≤ 5 minutes, all of which recovered spontaneous circulation, indicating the effectiveness of PP-CPR technology. In terms of final outcome, 4 patients (16.0%) died and 21 patients (84.0%) survived, indicating that PP-CPR technology could provide timely blood circulation and improve clinical outcomes for prone cardiac arrest patients. Among the 11 patients who reported complications after resuscitation, no neurological damage was found in the short-term outcomes, indicating that PP-CPR technology had a certain level of safety.Conclusions:PP-CPR can provide timely blood circulation for patients with cardiac arrest who are unable to lie supine quickly, and win "golden time" for defibrillation and further treatment. In clinical practice, medical staff need to evaluate the emergency environment, the number of rescuers and the specific condition of the patient, and implement first aid as soon as possible, so as to reduce the time of no blood flow in the vital organs of patients with cardiac arrest in prone position, and improve the clinical prognosis.

OBJECTIVE To investigate the damage effect and mechanisms of cyclophosphamide(CTX)and its active metabolite derivative 4-hydroperoxycyclophosphamide(4-HC)to human neuroblas-toma SH-SY5Y cells.METHODS SH-SY5Y cells were treated with CTX[0(cell control),0.01,0.1,1,5,10,20,40 and 80 mmol·L-1]and 4-HC[0(cell control),0.01,0.1,1,5,10,20,40 and 80 μmol·L-1]for 48 h.Cell confluence and morphology were observed by the IncuCyte ZOOM system.Cell viability was assessed by CCK-8 assay.Lactate dehydrogenase(LDH)release was measured by LDH assay kit.SH-SY5Y cells were treated with CTX(0,1,5,10 and 20 mmol·L-1)and 4-HC(0,1,5,10 and 20 μmol·L-1)for 48 h before cell proliferation was analyzed by 5-ethynyl-2′-deoxyuridine(EdU)staining assay.Immunofluorescence was employed to assess the levels of the DNA double-strand break marker γ-H2AX and to evaluate changes in mitochondrial membrane potential.SH-SY5Y cells were treated with CTX(0,1,5 and 10 mmol·L-1)and 4-HC(0,1,5 and 10 μmol·L-1)for 48 h,and the alterations in glycolysis and oxidative phosphorylation levels were analyzed using the Seahorse XFe96 Analyzer.RESULTS Compared with the cell control group,cell confluence and cell viability were significantly reduced in the CTX and 4-HC groups(P<0.01),and the half-maximal inhibitory concentrations(IC50)for CTX and 4-HC were 4.44 mmol·L-1 and 4.78 μmol·L-1,respectively.The release rate of LDH was signif-icantly increased while the percentage of EdU+cells was significantly reduced in the CTX and 4-HC groups(P<0.01).The percentage of γ-H2AX+cells was significantly increased and mitochondrial membrane potential significantly decreased in the CTX and 4-HC group(P<0.05).Treatment with CTX and 4-HC resulted in reduced levels of maximum glycolytic capacity,glycolytic reserve,maximal respi-ration,and ATP production(P<0.05).CONCLUSION CTX and 4-HC exert significant cytotoxic effects on SH-SY5Y cells by disrupting cell membrane structure,impeding cell proliferation,and reducing cell viability.The mechanisms underlying these effects may involve intracellular DNA damage,disturbance of energy metabolism and mitochondrial dysfunction.
